GAS-BURNING HEATER.

To all whom it may concern:

'Be it known that I, Jenn Cj TATE, a citizen of the United States, and a resident of the city of Oakland, county of Alameda and State of California, have made a new and useful invention-'to wit, Gas-Burning I-Ieaters; and I do declare the following to be a full, clear, exact, and concise description of the same.

'The invention relates particularly to gas burning heaters of the type disclosed in my United States Letters Patent, No. 1,181,552, dated May 2, 1916.

Among the objects of the invention are to render available all of the heat units contained within the fuel, to reproccss and renormalize the products of combustion, whereby none but innocuous fumes escape from the heater dispensing with outside fines or vents, rendering the heater one hundred per cent. ei'licient by transmuting all of the heat units of the fuel into available calories for radiation. Other objects and advantages will ap pear as this description progresses.

In this specification and the annexed drawings, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form because it may be embodied in other forms, and it is also to be understood that in and by the claim fol lowing the description it is desired to cover the invention in whatever form it may be embodied.

In the accompanying one sheet of drawings:

Figure l is a side view in cross section taken on the line II, Fig. 2, of a renormalizing gas heater constructed in accordance with this invention.

Fig. 2 is a front view of the same in cross section on the lines II-II, Fig. 3.

'Fig. 3 is a cross section of the same taken on the lines III-III, Fig. 2, looking down into the heater.

In detail the construction illustrated in the drawingsincludes an iron gas heater of the radiator type, having a central primary combustion chamber 1, with an-open bottom at 2, for the admission of atmospheric air as contained within the room to be heated.

or manufactured gas mixed with air and liberated through the openings 7, where it may be conveniently ignited through the opening 8 in the front of the combustion chamber, by the introduction of a lighted match or taper in'the usual manner. A similar opening 9 is provided for observation. Burners ofthis type consuming natural gas or gases made from oil or coal and other carbons, give off a clear blue smokeless flame but contain noxious elements, which it is one of the objects ofthis invention to normalize or neutralize. The flames issuing from the holes 7 impinge against the adjacent walls of the combustion chamber at 10 and 11, transmitting a relatively high degree of heat thereto in a'localized area. The products of combustion pass upward and out of the cen tral combustion chamber through the opcnings 12 and 13, thence downward through the circulating tubes 14 and 15, passing out of the bottom of these or through the openings 16 and 17, into the reheating chambers, arranged contiguous to and surrounding the hot walls 10 and 11 adjacent to the zone of the burner 3, preferably separated therefrom only by the walls of the combustion chamber. The reheating chambers intercommunicate through the rear. chamber 19, closed at the top by the wall 20 and at the bottom by the partition 21 and from which the products of combustion escape through the flanged opening 22. This outlet 22 leads to the revivifying chamber 23 consisting of a box-like structure having an opening inclos ing the outlet 22 over-spread by the screen 2+1, and having the outlet 25 facing inward toward the wall 26 of the combustion chamber. The revivifying chamber 23 fastened to the body of the radiator by the bracket 27. This revivifying chamber 23 is filled with a revivifying compound 28 fab ricated into balls or lumps adapted to permit the free circulation there among of the products of combustion passing through the chamber 23.

In connection with the revivifying compound, attention is directed to my co-pending application for patent entitled Absorb ing and purifying composition, Ser. No. 121,482, filed Sept. 22, 1916.

This invention operates substantially as follows: The products of combustion rlsing from the burner 3 and returning through the tubes 14. and 15 to the reheating chambers, are heated and processed therein.

The reheating causes a rarefication orsuction, similar to that caused within a chimney or fine after it becomes thoroughly heated, resulting in a thermo-siphon effect drawing a large volume of normal air through the opening 2, past the deflector 2, at the bottom of the combustion chamber, which rises and mingles with the products of combustion, causing a draft through the radiator that will eventually circulate all of the air within a. closed roomthrough the heater, thus raising the temperature of the whole volume by absorption of heat given off by the heater. The products of natural and commercial gas for combustion are known to contain noxious fumes, and a largevolume of moisture that is decom posed within the heater. and hydrogen. 1s

formed; this aids in prevent-ingthe condensation on the (201a walls. of the room, an. economic disadvantage that 1s wholly el'1m1..

nated by this invention, partly by contact with the hot walls 10 and 11 of the reheating chambers,by absorption in the compound 28, and bybeing liberated through the outlet 25 directly against the heated wall 26 of the combustion chamber. This recontacting of the products of combustion with surfaces of relatively high temperature has the double advantage of drying the air and increasing the speed of thermo-circulation or the siphoning effect through the heater. Perfect combustion within the heater is insured by the reheating or secondary combustion within the reheating chambers, yet there still remains the noxious 'fumes resulting even from perfect combustion that can not be disposed of as waste products, because of their calorific value, but which I have demonstrated can be neutralized and the atmosphere completely revivified without appreciable economic loss.

compound 28.

Without in any way limiting the scope of my invention and discovery, the following explanation of the phenomena is offered as tending to a better understanding of the invention, that is now a demonstrated success and in wide commercial use.

The resultant action of the products of combustion of gas containing sulfurous combinations, coming from the combustion chamber and mixed with the excess of normal atmosphere passing through the. open ing 2 and adjacent to the gas flame, is a combination that acts on the iron of the radiator, and produces oxids. The mass-body of gases of combustion, sulfuretted moisture of burned gas, and the unchanged heated atmosphere pass through the reheating chambers 18, wherein hydrogen maybe 23' carrying the said oxids in'atmospheric suspension, depositing them in the compound 28 by the precipitating action due to the separation of the-oxygen of the unformation of ozone.

' ture driven off in thecombustion of fuel in the combustion chamber takes placein the reheating chambers in the following manner. The uncombusted results and the moisture of the gas fuel after semi-oxidation in the iron radiator comes in contact with the hot partitions 10-1l between the primary combustion chamber and the reheating chambers, hydrogen is produced, and the heat created is sufficient tocomplete the primary combustion and further deodorize the fumes produced by the primary combustion, and put them in a state susceptible to chemical change by the compound 28 in the purifying chamber, which is the final revivification of the atmosphere taken in at the inlet 2 of the combustion chamber.

The sensed freshness of the heated atmosrelation in the atmosphere. This interpre-.

tation seems to be substantiated by the fact that the compound increases in weight,

which is the combined result of oxidization decomposition and absorption, and the further fact that there are no-odors or noxious fumes emitted. This compound is trifling' in first cost, and will retain its capacity throughout SIX monthsor more of continuous operation. The revlvificat-ion is more perfect in combination with the reprocessing of the products of combustion in the which is in a measure dependent upon the j quality of fuel consumed, f 7

, Having thus described my ''invention, what I claimand desire to secure by Let tors Patent is:

In a heater of the character described, an upstanding combustion chamber provided at its lower end with an air inlet, a burner extending transversely within the lower 7 portion of the combustion chamber and having sets of apertures arranged upon the opposite sides of its longitudinal ELXIS ior pro- 'viding flames which impinge against the sides of said combustion chamber, upstanding tubes arranged outwardly of and near the combustion chamber and having their upper ends in communication therewith while their lower ends are free from communication with the combustion chamber, reheating chambers arranged contiguous to the side walls of the combustion chamber, said extensions having their lower ends open and in communication with the lower ends of said tubes, and a revivifying chamber connected with the reheating chambers and receiving the highly heated gases therefrom, said revivifying chamber being adapted for the reception of chemical material and having an outlet opening near its top and upon the inner side thereof adjacent the heated wall of the combustion chamber. In testimony whereof I have hereunto set my hand at San Francisco, California, this 25th day of February, 1918.
